Skylights Maintenance Tips and Tricks

Skylights Maintenance Tips and Tricks 1

Skylights can add natural light, ventilation, and a sense of spaciousness to any room. However, without proper maintenance, they may also cause leaks, drafts, and other problems. In this article, we will share some skylights maintenance tips and tricks that can extend their lifespan, prevent damage, and ensure optimal performance.


One of the simplest yet most important skylights maintenance tips is regular cleaning. Dirt, dust, and debris can accumulate on the skylight surface, obstruct sunlight, and cause scratches or discoloration. To clean your skylight, follow these steps:

  • Use a soft-bristle brush or a lint-free cloth to remove loose dirt and dust.
  • Apply a mild detergent solution to the skylight surface, avoiding the edges and the sealant.
  • Rinse off the soap with clean water, using a squeegee or a soft cloth to remove excess water.
  • Dry the skylight frame and the surrounding area with a towel.
  • It is recommended to clean your skylight at least twice a year, or more often if you live in a dusty or polluted area. Avoid using abrasive or acidic cleaning products, as they may scratch or damage the skylight surface.


    Another crucial skylights maintenance tip is sealing. Skylights are prone to leaks, especially if they are installed on a flat or low-pitched roof, or if they are exposed to extreme weather conditions. To prevent leaks, make sure that your skylight is properly sealed and that the sealant is in good condition. Here’s how:

  • Inspect the skylight sealant regularly for cracks, gaps, or wear.
  • If you notice any damage, remove the old sealant with a scraper or a knife.
  • Clean the skylight edges and the contact surface with a degreaser and let it dry completely.
  • Apply a fresh layer of sealant, using a caulking gun and following the manufacturer’s instructions.
  • Smooth the sealant with a wet finger or a tool to ensure even coverage and adhesion.
  • By maintaining the sealant of your skylight, you can prevent water infiltration, air leakage, and energy loss. It is recommended to reseal your skylight every 5-10 years, depending on the type and quality of the sealant, as well as the age and condition of your skylight.


    Skylights can also contribute to heat gain or loss, depending on their orientation, glazing, and insulation. To improve the energy efficiency of your home and reduce your utility bills, consider adding insulation to your skylight. Here’s how:

  • Check the insulation level around your skylight, using a thermal imaging camera or a heat gun.
  • If you notice any gaps or leaks, remove the old insulation with a vacuum or a scraper.
  • Cut a piece of foam insulation, fiberglass insulation, or spray foam insulation to fit the gap.
  • Install the insulation firmly and snugly, leaving no gaps or spaces.
  • Insulating your skylight can help regulate the indoor temperature, reduce condensation, and minimize sound transmission. It is recommended to consult a professional installer or contractor for more complex or large-scale insulation projects.


    Maintaining your skylights can not only enhance their appearance and functionality but also protect your investment and ensure your safety and comfort. By following these skylights maintenance tips and tricks, you can enjoy the benefits of natural light and fresh air, without worrying about leaks, drafts, or energy waste.
